THE CYBERSWITCH

Interoperability Overview

The CyberSWITCH supports the following PPP protocols:

•Link Control Protocol (LCP)

•Multilink Protocol (MLP)

•Authentication Protocols

Challenge Handshake Authentication Protocol (CHAP)

Password Authentication Protocol (PAP)

•Network Control Protocols (NCP)

Internet Protocol Control Protocol for TCP/IP (IPCP)

Internetwork Packet Exchange Control Protocol for IPX (IPXCP)

Bridge Control Protocol for bridges (BCP)

•Compression Control Protocol (CCP)

•AppleTalk Control Protocol (ATCP)

The CyberSWITCH supports the following AppleTalk protocols:

•EtherTalk Link Access Protocol (ELAP)

•AppleTalk Address Resolution Protocol (AARP)

•PPP AppleTalk/AppleTalk Control Protocol (ATCP)

•Datagram Delivery Protocol (DDP)

•Routing Table Maintenance Protocol (RTMP)

•AppleTalk Echo Protocol (AEP)

•Name Binding Protocol (NBP)

•Zone Information Protocol (ZIP)

INTEROPERABILITY DEVICES

Remote devices that may connect to the CyberSWITCH include the following:

•MAC Layer Bridges

•IP Host Devices

•IP Router Devices

•IPX Routers

•AppleTalk Routers

MAC layer bridges connect to the system using the HDLC bridge encapsulation line protocol. These devices send transparently bridged Ethernet frames to the system. MAC layer bridges do not process network layer protocols. They forward all packets based on source and destination MAC addresses.

IP Host devices are single workstations or PCs that connect to the system at the IP network layer. These devices use either the RFC1294 based protocol or PPP to communicate with the system.

IP router devices are single devices that represent many other IP hosts and routers to the system. They must use the CHAP or PAP protocol to identify themselves to the system. IP routers usually provide IP network address information at connection time (and use PPP to send user data to the system).

IPX routers are single devices that perform network layer tasks (addressing, routing, and switching) to move packets from one location on the network to another. IPX routers use the Internetwork Packet Exchange (IPX) protocol, typical of the NetWare environment.

AppleTalk routers route AppleTalk datagrams based on address information. They support the following protocols: RTMP, NBP, and ZIP.
